Turbomachinery Package Specification

Taurus 60 Compressor Set and Mechanical Drive

 

 

16 Marinization

16.1General Description

The Taurus 60 Compressor Set and Mechanical Drives may be operated in offshore oil and gas applications. Depending upon operating conditions and movement of the underlying support structure, optional package modifications may be required. Solar turbomachinery packages operate successfully on the following types of offshore installations:

•Fixed Platform (FP)

•Tension Leg Platform (TLP)

•Compliant Tower (CT)

•Spar Platform (SP)

•Semi-submersible Platform (SSP)

•Floating Production Systems (FPS)

•Floating Production, Storage and Offloading (FPSO)

•Mini-Tension Leg Platform (Mini-TLP)

Applications are evaluated based on the expected motion severity and the degree of package mounting surface flexing. Solar offers the following package modifications to achieve successful long-term operation. Refer to Solar’s Engineering Specification ES2379 for additional information.

16.1.1Gimbals (Optional)

Gimbals provide protection against G-forces generated by vessel pitch and roll movements and against deflection, twisting, and thermal growth of the mounting deck. Gimbals may be used for three-point package mounting.

16.1.2Anti-Vibration Mounts (Optional)

Anti-vibration mounts (AVMs) are used to isolate the mounting surface from package- generated vibrations. AVMs do not provide the same level of motion protection as gimbals. AVMs may be used for three-point package mounting.

16.1.3Internal Package Modifications

Moderate or severe package motion can potentially interfere with lube oil system operation. To prevent interference, modifications may be made to the lube oil system to ensure proper lube oil circulation.

16.1.4Inclinometers

For moderate and severe duty applications, an inclinometer is furnished to provide alarm annunciation and equipment shutdown inputs when maximum allowable angular displacements are exceeded. Alarm levels are typically set 2 degrees below shutdown levels.

16.1.5Certification

Certification is typically required to demonstrate offshore turbomachinery compliance with applicable rules for a fixed or mobile offshore installation. Solar can provide the necessary certification or assist the customer in obtaining certification. Involvement of one of the following certifying authorities is usually required:

•Det Norske Veritas (DNV)
